Description

Technical Field

[0001] (Related Application) This application claims priority from Chinese patent applications with filing dates of March 21, 2023, application numbers of 202310282140.1, invention titles of "Storage Member and Refrigerator Having the Same", filing dates of March 21, 2023, application numbers of 202310280484.9, invention titles of "Storage Member and Refrigerator Having the Same", and filing dates of March 21, 2023, application numbers of 202310282115.3, invention titles of "Storage Member and Refrigerator Having the Same", and all of their contents are incorporated herein by reference.

[0002] The present invention relates to the technical field of household appliances, and particularly to a storage member and a refrigerator having the same.

Background Art

[0003] In household appliances (such as refrigerators), when the door body is opened, the opening angle of the door body increases as the opening process progresses. In the prior art, due to the structure based on fixed-axis rotation, the opening angle of the door body increases uniformly, and the rotation of the entire door body also progresses uniformly as the opening angle increases. However, in this method, the rotation or swinging process of the door body becomes unstable.

Summary of the Invention

[0004] One object of the present invention is to provide a storage member for solving the technical problem of instability in the door body rotation process in the prior art.

[0005] Another object of the present invention is to provide a refrigerator.

[0006] To achieve one of the above-described objectives of the invention, one embodiment of the present invention provides a storage member comprising a box, a door, and a hinge member. The door is rotatably connected to an opening in the box via the hinge member. The hinge member includes a main shaft, a secondary shaft that provides a guide for the rotation of the door, and a main groove and a secondary groove corresponding to (engaging with) the main shaft and the secondary shaft, respectively. During the rotation process of the door, there is a stage in which the secondary shaft moves as a whole along a linear secondary shaft trajectory.

[0007] As a further improvement of one embodiment of the present invention, during the opening process of the door body, the main shaft moves along the third main shaft trajectory while the sub-shaft moves along the first sub-shaft trajectory. Here, the third main shaft trajectory is curved as a whole, and the first sub-shaft trajectory is straight as a whole.

[0008] As a further improvement of one embodiment of the present invention, the storage member is positioned on the side of the external environment member. The door body includes a second wall surface. When the door body closes the opening of the box body, the hinge member is close to the first side surface of the external environment member, and the second wall surface is close to and parallel to the first side surface. In the process of opening the door body, the sub-axis moves sequentially along a third sub-axis trajectory and a fourth sub-axis trajectory relative to the door body. The third sub-axis trajectory is linear as a whole, the fourth sub-axis trajectory is curved as a whole, and the fourth sub-axis trajectory is located on the side of the third sub-axis trajectory that is close to the second wall surface.

[0009] As a further improvement of one embodiment of the present invention, the storage member is positioned on the side of the external environment member. The door body includes a second wall surface. When the door body closes the opening of the box body, the hinge member is close to the first side surface of the external environment member, and the second wall surface is close to and parallel to the first side surface. In the closing process of the door body, the sub-axis has a step in which it moves sequentially along a first sub-axis trajectory and a fourth sub-axis trajectory. The first sub-axis trajectory is straight as a whole, the fourth sub-axis trajectory is curved as a whole, and the fourth sub-axis trajectory is located on the side of the first sub-axis trajectory away from the second wall surface.

[0010] To achieve one of the above-mentioned objectives of the invention, one embodiment of the present invention provides a refrigerator including a storage member described in any of the above-mentioned technical solutions. [Effects of the Invention]

[0011] Compared with conventional technology, the storage member provided by the present invention can improve rotational stability by setting a stage in which the sub-shaft moves linearly during the rotation (pivot) or swinging process of the door body. [Brief explanation of the drawing]

[0013] The present invention will be described in detail below based on the specific embodiments shown in the drawings. However, these embodiments are not intended to limit the present invention, and any structural, method, or functional modifications made by those skilled in the art based on these embodiments are all covered by the present invention.

[0014] Furthermore, the term "includes" or other variations of it means non-exclusive inclusion, meaning that a process, method, article, or apparatus containing a set of elements includes not only those elements but also other elements not explicitly listed, or elements specific to such process, method, article, or apparatus. Also, terms such as "first," "second," "third," "fourth," "fifth," "sixth," and "seventh" are used for explanatory purposes only and should not be understood as suggesting relative importance.

[0015] One embodiment of the present invention provides a refrigerator including one of the following storage components:

[0016] The refrigerator may include storage compartments at different temperature ranges and a refrigerator door for opening and closing these compartments. Generally, a refrigerator has a refrigerator compartment at a temperature of 0 degrees Celsius or higher, a freezer compartment at a temperature of 0 degrees Celsius or lower, and a refrigerator door for opening and closing each of the refrigerator and freezer compartments. In one embodiment, a storage member can be used to constitute the refrigerator door and the refrigerator compartment or the freezer compartment.

[0017] As shown in FIGS. 1 and 2, an embodiment of the present invention provides a storage member including a box body 100, a door body 200, and a hinge member 300.

[0018] The door body 200 is swingably connected to the opening 10 of the box body 100 via the hinge member 300, and realizes the opening and closing of the door body 200 with respect to the internal storage space of the box body 100.

[0019] FIG. 2 is a top view of the storage member in a state where the door body 200 is opened to a certain angle, and FIG. 3 is a partial enlarged view of the A region in FIG. 2. FIGS. 4 to 10 are also partial enlarged views of the A region in FIG. 2, but it can be understood that each shows the door body 200 in a state of being opened to another angle.

[0020] FIG. 3 shows an embodiment of the present invention. The hinge member 300 includes a main shaft 31, the hinge member 300 includes a sub-shaft 32, and the hinge member 300 further includes a main groove 21 corresponding (engaging) to the main shaft 31 and a sub-groove 22 corresponding (engaging) to the sub-shaft 32.

[0021] The main shaft 31 is used for adjusting the position of the door body 200, for rotationally driving the door body 200, for adjusting the positional relationship between the door body 200 and the box body 100, and for realizing the translational movement of the door body 200. In the opening and closing process of the door body 200, one side (opening and closing side) of the door body 200 is separated from the connection with the box body 100, and the other side (shaft support side 201) maintains the connection relationship with the box body.

[0022] The main shaft 31 is used to control the movement of the door body 200. If hinge members 300 are provided at both ends of the pivot side (swinging side) 201 of the door body 200, the main shaft 31 can be specifically used to control the parallel movement of the door body 200. For example, parallel movement toward or away from the box body 100, or parallel movement toward or away from the opening 10. Proximity to the box body 100 means that at least the pivot side 201 of the door body 200 has a movement component toward the box body 100, or that the position of the door body 200 with parallel movement toward the box body 100 when opened to the same angle is closer to the box body 100 compared to the door body 200 that rotates in place on a fixed axis. "Apart from the box body 100" means that at least the pivot support side 201 of the door body 200 has a component of movement in the direction away from the box body 100, or that the position of the door body 200, which has parallel movement toward the box body 100, when opened to the same angle is greater than that of the door body 200 which rotates in its original position on a fixed axis.

[0023] The sub-shaft 32 is used to guide the rotation of the door body 200.

[0024] The sub-shaft 32 is used to guide the door body 200 to rotate simultaneously with its movement, and / or to assist in the movement control of the door body 200 by the main shaft 31.

[0025] In one embodiment, with the door body 200 closed, the main shaft 31 is positioned away from the opening 10 with respect to the sub-shaft 32. In an embodiment in which the storage member is positioned close to the external environment member 400, the door body 200 can be positioned close to the external environment member 400 specifically via its pivot side, and in this case, the main shaft 31 is positioned close to the external environment member 400 with respect to the sub-shaft 32. The storage member is positioned on the first side 401 of the external environment member 400, and a space for housing the storage member is provided on the first side 401 of the external environment member 400. With respect to the opening and closing side of the door body 200, the pivot side 201 of the door body 200 is closer to the external environment member 400.

[0026] In one embodiment, the extended length of the main groove 21 is shorter than the extended length of the sub-groove 22, and in the process of opening the door body 200 from a closed state to its maximum angle relative to the box body 100, the travel distance of the main shaft 31 is less than or equal to the travel distance of the sub-shaft 32.

[0027] In one embodiment, during the swinging process of the door body 200, there is a stage in which the sub-shaft 32 as a whole moves along a linear sub-shaft trajectory. This ensures stability during the swinging process.

[0028] The swinging process of the door body 200 includes swinging open and / or swinging closed. During the swinging process, movement states such as rotation in position, translation, and combinations of translation and rotation can be formed, having different amplitudes, different amounts of translation, or different amounts of rotation.

[0029] As shown in Figure 8, during the process of the door body 200 opening, the main shaft 31 moves along the third main shaft trajectory line 53, and at the same time, the secondary shaft 32 moves along the first secondary shaft trajectory line 64.

[0030] During the process of the door body 200 opening, there are simultaneously stages in which the main shaft 31 moves along the third main shaft trajectory line 53 and the secondary shaft 32 moves along the first secondary shaft trajectory line 64.

[0031] The third main axis trajectory line 53 is curved as a whole, and may be a single circular arc, a combination of multiple circular arcs, or an irregularly curved shape as a whole. The first secondary axis trajectory line 64 is straight as a whole, and may be a single straight line, or may be formed by a combination of multiple straight sections.

[0032] In this way, by configuring the trajectory corresponding to the sub-shaft 32, which acts as a guide, as a straight line, the normal rotation of the door body 200 can be guaranteed, stability during the opening process of the door body 200 can be improved, and problems such as interference due to machining errors in the long curved section and damage due to structural deterioration over time can be avoided. At the same time, by configuring the trajectory corresponding to the main shaft 31, which acts as the drive, as a curve, the door body 200 can be opened horizontally at the same angle with a smaller positional movement of the main shaft 31, and the swinging opening process of the door body 200 becomes more stable due to the smaller positional movement of the main shaft 31.

[0033] In one embodiment, the special arrangement of the main shaft 31 and sub-shaft 32 described above can be realized after the door body 200 has opened to 90 degrees. That is, as shown in Figures 7 and 8, in the process of the door body 200 opening further from 90 degrees, the main shaft 31 moves along the third main shaft trajectory line 53, while the sub-shaft 32 moves along the first sub-shaft trajectory line 64. This makes the process of opening to large angles beyond 90 degrees more stable, and in particular the movement and guiding of the sub-shaft 64 side can be made more stable, so that even when it is necessary to store items in the door body 200, it can still be opened to a large angle stably.

[0034] As shown in Figures 5 and 3 or 9, in the process of opening the door body 200, the sub-shaft 32 has a stage of moving sequentially along a third sub-shaft trajectory line 63 and a stage of moving along a fourth sub-shaft trajectory line 62 relative to the door body 200. In one embodiment, after completing the stage of moving along the third sub-shaft trajectory line 63, the sub-shaft 32 immediately enters the stage of moving along the fourth sub-shaft trajectory line 62. In another embodiment, after completing the stage of moving along the third sub-shaft trajectory line 63, the sub-shaft 32 moves along a plurality of other sub-shaft trajectory lines and then enters the stage of moving along the fourth sub-shaft trajectory line 62.

[0035] The third secondary axis trajectory line 63 is straight as a whole, and may be a single straight line or formed by a combination of multiple straight sections. The fourth secondary axis trajectory line 62 is curved as a whole, and may be a single circular arc, a combination of multiple circular arcs, or an irregularly curved shape.

[0036] This makes it possible to first generate the amount of movement of the door body 200 when the sub-shaft 32 moves in a straight line, and then assist in generating the amount of rotation of the door body 200 when the sub-shaft 32 moves in a curve.

[0037] The aforementioned trajectory arrangement allows for initially increasing the proportion of movement of the door body 200, and then increasing the proportion of rotation of the door body 200. This allows for adjusting the ratio of rotation and movement of the door body 200 according to different opening states of the door body 200, thereby achieving both interference prevention in the initial stages, rapid release of space in the middle and later stages, and large-angle opening.

[0038] As shown in Figures 8, 7, and 6, during the closing process of the door body 200, the sub-shaft 32 sequentially moves along a first sub-shaft trajectory line 64 and then along a fourth sub-shaft trajectory line 62 relative to the door body 200. In one embodiment, after completing the movement step along the first sub-shaft trajectory line 64, the sub-shaft 32 immediately enters the movement step along the fourth sub-shaft trajectory line 62. In another embodiment, after completing the movement step along the first sub-shaft trajectory line 64, the sub-shaft 32 moves along a plurality of other sub-shaft trajectory lines and then enters the movement step along the fourth sub-shaft trajectory line 62.

[0039] The first secondary axis trajectory line 64 is straight as a whole, and may be a single straight line or formed by a combination of multiple straight sections. The fourth secondary axis trajectory line 62 is curved as a whole, and may be a single circular arc, a combination of multiple circular arcs, or an irregularly curved shape.

[0040] This makes it possible to assist in the closing process by first generating a movement of the door body 200 when the sub-shaft 32 moves linearly, and then generating a rotation of the door body 200 when the sub-shaft 32 moves in a curved direction.

[0041] As described above, the trajectory arrangement allows for a larger proportion of the door body 200's movement during the closing process, followed by a larger proportion of its rotation. This allows for adjusting the ratio of rotation and movement of the door body 200 according to different closing states, achieving both interference prevention in the initial stages of closing and rapid closing and rotation of the opening in the middle and later stages.

[0042] In one embodiment, as shown in Figures 4 and 5, the storage member is positioned on the side of the external environment member 400, and the door body 200 includes a second wall surface 24.

[0043] When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 is close to the first side surface 41 of the external environment member 400, the second wall surface 24 is close to the first side surface 41, and the second wall surface 24 is parallel to the first side surface 41. This allows us to define the relationship between each wall surface on the door body 200.

[0044] The door body 200 includes a first wall surface 23 and a second wall surface 24 that are perpendicular to each other. The first wall surface 23 is close to the plane in which the opening 10 is located, and the second wall surface 23 is basically parallel to the plane in which the opening 10 is located.

[0045] The external environmental member 400 may be any part that could potentially interfere with the swinging opening of the door body 200. For example, if the storage member is arranged vertically, the external environmental member 400 may be a wall surface adjacent to the storage member, an internal wall of the storage unit, etc. If the storage member is arranged horizontally, the external environmental member 400 may be a floor surface, a baseboard, or an internal wall of the storage unit, etc.

[0046] The first side surface 41 may be the side surface in the external environment member 400 that is close to the box body 100 and / or door body 200. The parallelism includes at least two types: exact parallelism and approximate parallelism (angle less than a set range), and whether or not it is exact parallelism depends on the shape and flatness of the door body 200, the shape and flatness of the opening 10, and the shape and flatness of the first side surface 41. The plane on which the opening 10 exists refers to the plane of the box body 100 that the user faces when taking something out of the opening 10, and in the top view shown in Figures 3 to 10, the plane on which the opening 10 exists can refer to the plane that extends laterally in the opening 10.

[0047] When the door body 200 closes the opening 10 of the box body 100, the first wall surface 23 is close to and parallel to the plane on which the opening 10 exists. This allows us to define the relationship between each wall surface on the door body 200. In the figure, the first wall surface 23 is shown as a wall surface on the main body of the door body 200, excluding the door seal structure, that is close to and parallel to the plane on which the opening 10 exists. However, in some embodiments, the door body 200 can be defined as a whole component including the door seal, in which case the first wall surface corresponds to a part of the door seal.

[0048] The main axis trajectory line 5 may include the third main axis trajectory line 53, as shown in Figures 8 and 7.

[0049] In the process of the door body 200 opening and the main shaft 31 moving along the third main shaft trajectory line 53, there is a stage in which the main shaft 31 moves in a direction toward the second wall surface 24 while moving toward the first wall surface 23 relative to the door body 200. In an embodiment in which the main shaft 31 is fixed to the box body 100, based on the principle of relative movement, the second wall surface 24 can move toward the main shaft 31, and the first wall surface 23 can move toward the main shaft 31. This makes it possible to control the direction of movement of the wall surface and its associated ridges.

[0050] To simplify the explanation, we define the direction approaching the external environmental member 400 as "outward," the direction away from the external environmental member 400 as "inward," the direction approaching the box body 100 as "backward," and the direction away from the box body 100 as "forward."

[0051] On the other hand, when the perpendicular from the center point of the main shaft 31 to the second wall surface 24 has a component that extends in a direction parallel to the first side surface on the external environment member 400 (i.e., a component that extends in the vertical or longitudinal direction as shown in Figure 8), the second wall surface 24 is close to the main shaft 31 at this time, and therefore the second wall surface 24 can be considered to have the forward movement component. As a result, the ridges formed by the intersection of the second wall surface 24 and the other wall surfaces of the door body 200 (for example, the first side ridge and the second side ridge described later) all have an inward movement component, and when the door body 200 is opened to a large angle, it is possible to prevent the ridges or wall surfaces from pressing against the box body 100 and causing interference or damage.

[0052] As can be seen, the change in the perpendicular from the center point of the principal axis 31 to the second wall surface 24 can determine the movement of the second wall surface 24 and its associated edges. For example, if the length of the perpendicular from the center point of the principal axis 31 to the second wall surface 24 increases, it indicates that the principal axis 31 and the second wall surface 24 are moving relatively apart, at least in the direction in which the perpendicular extends. Conversely, for example, if the length of the perpendicular from the center point of the principal axis 31 to the second wall surface 24 decreases, it indicates that the principal axis 31 and the second wall surface 24 are moving relatively closer together, at least in the direction in which the perpendicular extends. Based on this, the perpendicular from the center point of the principal axis 31 to the second wall surface 24 can be viewed as a line segment with direction, that is, the perpendicular can be viewed as a vector. Therefore, below, the perpendicular from the center point of the principal axis 31 to the second wall surface 24 is defined as the second vector perpendicular.

[0053] In one embodiment, the perpendicular line from the center point of the principal axis 31 to the first wall surface 23 can be defined as the first vector perpendicular.

[0054] When the first vector perpendicular has a component extending perpendicular to the first side surface on the external environment member 400 (i.e., a component extending horizontally or laterally as shown in Figure 9), the first vector perpendicular points away from the principal axis 31, and therefore the first wall surface 23 can be considered to have the inward movement component. As a result, the first wall surface 23 and the ridges formed by its intersection with other wall surfaces of the door body (for example, the second side ridge formed by its intersection with the second wall surface 24) all have inward movement components, which helps to open to a larger angle while simultaneously preventing interference with the external environment member 400, etc.

[0055] When viewed in conjunction with other vector perpendiculars, the second wall surface 24 moves forward and outward as a whole, while the first wall surface 23 moves inward and forward as a whole.

[0056] Correspondingly, during the closing process of the door body 200, as the main shaft 31 moves along the third main shaft trajectory line 53 relative to the door body 200, the main shaft 31 moves away from the second wall surface 24 while approaching the first wall surface 23. The second wall surface 24 moves backward and inward as a whole, and the first wall surface 23 moves outward and backward as a whole. This allows the door body 200 to quickly return from a large angle state, and in particular, because both the second wall surface 24 and the first wall surface 23 move backward, it is possible to control the excessive protrusion of the free end of the door body 200 due to the movement of the rotating end surface during the closing process, and the door body can be quickly rotated and closed by the two mutually perpendicular wall surfaces moving in different directions, "inward" and "outward".

[0057] As shown in Figures 9, 6, and 7, the fourth sub-axis trajectory 62 is positioned on the side of the third sub-axis trajectory 63 that is close to the second wall surface 24. This allows the sub-axis 32 to first move along the straight third sub-axis trajectory 63 during the door opening process, and then maintain a curved movement in one direction toward the second wall surface 24, thereby deepening the degree of door opening, improving the smoothness of the shaft groove engagement, and avoiding structural deterioration and damage due to interference over time.

[0058] In one embodiment, during the process of switching from movement along the third sub-axis trajectory 63 to movement along the fourth sub-axis trajectory 62, the angle between the direction of movement of the sub-axis 32 and the second wall surface 24 gradually increases from an acute angle. As a result, the transition between the third sub-axis trajectory 63 and the fourth sub-axis trajectory 62 becomes more continuous and smooth, there are no abrupt changes in angle during the trajectory switching process, and the gradual increase from an acute angle makes the process of deepening the rotational opening of the door body 200 more stable, which can assist in subsequent opening to a larger angle.

[0059] As shown in Figures 8, 7, and 6, the fourth sub-axis trajectory line 62 is positioned as a whole on the side of the first sub-axis trajectory line 64 that is away from the second wall surface 24. This allows the sub-axis 32 to first move along the straight first sub-axis trajectory line 64 during the door closing process, and then maintain a curved movement away from the second wall surface 24 in one direction, thereby increasing the amplitude of the door closing, improving the smoothness of the shaft groove fitting, and avoiding structural deterioration and damage due to interference over time.

[0060] In one embodiment, during the process of switching from movement along the first sub-axis trajectory 64 to movement along the fourth sub-axis trajectory 62, the angle between the direction of movement of the sub-axis 32 and the second wall surface 24 gradually increases from an acute angle. As a result, the transition between the first sub-axis trajectory 64 and the fourth sub-axis trajectory 62 becomes more continuous and smooth, there are no abrupt changes in angle during the trajectory switching process, and the gradual increase from an acute angle makes the process of deepening the rotational opening of the door body 200 more stable, which can assist in subsequent opening to a larger angle.

[0061] As the door body 200 opens and the sub-shaft 32 moves along the first sub-shaft trajectory line 64, there is a stage in which the sub-shaft 32 moves in a direction that approaches the second wall surface 24 while moving away from the first wall surface 23 relative to the door body 200. As a result, the sub-shaft 32 approaches the second wall surface 24, deepening the rotational amplitude of the door body 200 and achieving the effect of large-angle opening. Furthermore, in the middle to later stages of rotational opening (for example, after the door body 200 has opened to 90 degrees), it is possible to control the further expansion of the rotational amplitude of the door body 200 and achieve large-angle opening of the door body 200.

[0062] In an embodiment where the first sub-axis trajectory line 64 is a straight line overall, the movement of the door body 200 during the large-angle opening process can be made more stable.

[0063] In an embodiment in which the sub-shaft 32 extends toward the midpoint of the side edge formed by the second wall surface 24 and the upper surface of the door body 200, the sub-shaft 32 corresponds to moving toward the mass center plane of the door body 200 (a plane passing through the mass center of the door body 200 and parallel to the front wall of the door), which makes the movement and stopping processes of the door body 200 more stable.

[0064] As shown in Figure 4, if we define the door body 200 as including a third wall surface 25, and the door body 200 closes the opening 10 of the box body 100, the third wall surface 25 is separated from the plane in which the opening 10 exists and is parallel to that plane. If we define the third wall surface 25 and the second wall surface 24 as intersecting to form a first side edge 26, then in the opening process of the door body 200 described above, the main shaft 31 moves along the third main shaft trajectory line 53 in a direction approaching the first side edge 26, and the sub-shaft 32 moves along the first sub-shaft trajectory line 64 in a direction approaching the first side edge 26, thereby enabling the movement process of the door body 200 to achieve both stability and large-angle opening.

[0065] In response to this, during the closing process of the door body 200, as the sub-shaft 32 moves along the first sub-shaft trajectory line 64, there is a stage in which the sub-shaft 32 moves away from the second wall surface 24 while approaching the first wall surface 23 relative to the door body 200. This allows the door body 200 to be closed stably and quickly.

[0066] In one embodiment, the storage member is positioned on the side of the external environment member 400. The storage member is positioned on the first side 401 of the external environment member 400, and a space for accommodating the storage member is provided on the first side 401 of the external environment member 400. The main shaft 31 is fixed to the box body 100, and the main groove 21 is fixed to the door body 200. As shown in Figures 4 and 5, the main shaft 31 can be specifically fixed to the box body 100 via a hinge plate 30. When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 is positioned closer to the external environment member 400. The storage member is positioned on the first side 401 of the external environment member 400, and a space for accommodating the storage member is provided on the first side 401 of the external environment member 400. With respect to the opening and closing side, the pivot side 201 of the door body 200 is closer to the external environment member 400.

[0067] In this embodiment, the side of the door body 200 that is close to the external environmental member 400 is designated as the pivot side 201. The pivot side 201 of the door body 200 may interfere with the external environmental member 400 during the door opening process.

[0068] The main shaft 31 can be fixed to the door body 200 or integrally molded with the door body 200. Correspondingly, the main groove 21 can be fixed to the box body 100, and the positions of the shaft and groove can also be swapped by forming the main groove 21 on the hinge plate 30.

[0069] The sub-shaft 32 can be fixed to the box body 100, and the sub-groove 22 can be fixed to the door body 200. Similar to the main shaft 31, the sub-shaft 32 can be fixed to the box body 100 via the hinge plate 30.

[0070] As the door body 200 opens, as shown in Figure 9, the main shaft 31 has a movement component relative to the door body 200 in the direction toward the external environment member 400. Based on the principle of relative movement, the door body 200 correspondingly has a movement component toward the direction toward the external environment member 400. As the door body 200 opens, the main shaft 31 moves toward the external environment member 400 relative to the door body 200. Based on the principle of relative movement, the door body 200 moves away from the external environment member 400.

[0071] This prevents interference between the door body 200 and the external environment member 400. When the main shaft 31 is installed on the door body 200, based on the above technical effects, the main shaft 31 can have a movement component in the direction away from the external environment member 400 relative to the box body 100.

[0072] In this case, there are no restrictions on the installation position or direction of movement of the sub-shaft 32, and the main shaft 31 does not necessarily need to move in a direction perpendicular to the external environmental member 400 (it is sufficient if there is a movement component that moves away from or closer to the external environmental member 400).

[0073] In one embodiment, as shown in Figures 8 and 4, the storage member is positioned on the side of the external environment member 400. When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 comes into close proximity to the external environment member 400. This defines the pivot side on which the door body 200 rotates using the hinge member 300.

[0074] As the sub-axis 32 moves along the first sub-axis trajectory line 64, there is a stage in which the door body 200 moves away from the external environment member 400. This helps the door body 200 to avoid interference with the external environment member 400 and establishes a positional foundation for the large-angle opening of the door body 200.

[0075] In one embodiment, when the sub-axis 32 moves along the first sub-axis trajectory line 64, there is a stage in which the door body 200 moves away from the external environment member 400 and away from the box body 100. This not only achieves the effects of both wide-angle door opening and interference prevention, but also prevents the upper part of the door body 200 (especially the first side ridge 26) from pressing against the box body 100.

[0076] The present invention is not limited to the door body 200 always having movement in the direction described above during the process of moving along the first sub-axis trajectory 64. Before the above-described movement step, the door body 200 may move in other directions as the sub-axis 32 moves along the first sub-axis trajectory 64, and / or after the above-described movement step, the door body may move in other directions as the sub-axis 32 moves along the first sub-axis trajectory 64.

[0077] In addition to the movement described above, the door body 200 can also rotate, and the present invention does not impose any limitations on this either.

[0078] In one embodiment, as shown in Figures 8 and 4, the storage member is positioned on the side of the external environment member 400, and the door body 200 includes a second wall surface 24. When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 is close to the first side surface 41 of the external environment member 400, the second wall surface 24 is close to the first side surface 41, and the second wall surface 24 is parallel to the first side surface 41. This allows the positional relationship of the second wall surface 24 on the door body 200 to be defined.

[0079] The main axis trajectory line 5 may include at least a curved portion, and that curved portion protrudes toward the side away from the second wall surface 24.

[0080] The curved portion may be a single arc, a combination of multiple arcs, or an arc-shaped curve.

[0081] The aforementioned arc shape may be a strictly defined arc shape, or it may be an approximate arc shape with deformation within a certain error range. Further explanation will not be provided below.

[0082] The protruding direction of the curved portion described above can be understood as follows: The intersection of perpendiculars between any two tangents on the curved portion is located on the side of the curved portion that is close to the second wall surface 24. The furthest point on the curved portion from the second wall surface 24 is located at a position other than the endpoints on the curved portion. The point of contact of a tangent parallel to the line connecting its two endpoints is located on the side of the line connecting the two endpoints that is away from the second wall surface 24. This allows the curved portion to not only provide smooth guidance for the movement of the door body 200, but also reduces the constraints on the shape of the sub-groove 22 for the rotation of the door body 200, and allows the sub-groove 22 to be configured in a shape that makes the movement of the door body 200 more stable. By having the curved portion protrude in the direction away from the second wall surface 24, based on the principle of relative movement, the second wall surface 24, which is the rotating end face, can first have a movement component that moves away from the main shaft 31, and then move closer to the main shaft, and the design of the movement trajectory of each edge of the second wall surface 24 becomes easier, improving the performance of interference prevention and avoiding impact on item retrieval.

[0083] The third main axis trajectory line 53 protrudes toward the side away from the second wall surface 24. The direction of protrusion of the third main axis trajectory line 53 described above can be understood as follows: The intersection of perpendiculars of any two tangents on the third main axis trajectory line 53 is located on the side of the third main axis trajectory line 53 that is close to the second wall surface 24. The point on the third main axis trajectory line 53 furthest from the second wall surface 24 is located at a position other than the endpoints on the third main axis trajectory line 53. The point of tangency of a tangent parallel to the line connecting its two endpoints is located on the side of the line connecting those two endpoints that is away from the second wall surface 24. As a result, the third main axis trajectory line 53 not only enables smooth guidance of the movement of the door body 200, but also reduces the constraint on the shape of the sub-groove 22 with respect to the rotation of the door body 200, and allows the sub-groove 22 to be configured in a shape that makes the movement of the door body 200 more stable. As the third main spindle trajectory line 53 protrudes away from the second wall surface 24, based on the principle of relative movement, the second wall surface 24, which is the rotating end face, can first have a movement component that moves away from the main spindle 31, and then move closer to the main spindle. Furthermore, the design of the movement trajectory of each edge of the second wall surface 24 becomes easier, improving the performance of interference prevention and avoiding impact on product retrieval.

[0084] The main axis trajectory line 5 is elliptical arc in shape as a whole. This results in a longer extension length and a better effect in preventing interference with the door body 200. On the one hand, the main axis trajectory line 5 can be configured as a standard elliptical arc, and the line connecting the two endpoints of the main axis trajectory line 5 may be parallel to the major axis of the elliptical arc, that is, the main axis trajectory line 5 as a whole is an axisymmetric figure and has a constant extension length. On the other hand, the main axis trajectory line 5 can be configured as a curved shape formed by a combination of multiple circular arcs and / or elliptical arcs and / or straight lines, and the present invention does not limit the combination method.

[0085] The aforementioned elliptical arc may be a strictly elliptical arc, or it may be an approximate elliptical arc with deformation within a certain error range. Further explanation will not be provided below.

[0086] The third main axis trajectory line 53 is elliptical arc in shape as a whole. This results in a longer extension length and a better effect in preventing interference with the door body 200. On the one hand, the third main axis trajectory line 53 can be configured as a standard elliptical arc, and the line connecting the two endpoints of the third main axis trajectory line 53 may be parallel to the major axis of the elliptical arc, that is, the third main axis trajectory line 53 as a whole is an axisymmetric figure and has a constant extension length. On the other hand, the third main axis trajectory line 53 can be configured as a curved shape formed by a combination of multiple circular arcs and / or elliptical arcs and / or straight lines, and the present invention does not limit the combination method.

[0087] The third main axis track line 53 can be configured as part of the main axis track line 5.

[0088] The main axis trajectory line 5 can be configured as a whole to have all the properties of the third main axis trajectory line 53 described above.

[0089] The transitions between different trajectory sections of the main axis trajectory line 5 are smooth.

[0090] In one embodiment, as shown in Figures 9 and 4, during the process of opening the door body 200, the main shaft 31 further moves along the first main shaft trajectory line 51.

[0091] The main shaft trajectory line 5 may include the first main shaft trajectory line 51. When the main shaft 31 moves along the first main shaft trajectory line 51 relative to the door body 200, the main shaft 31 moves closer to the second wall surface 24 while moving away from the first wall surface 23. In an embodiment in which the main shaft 31 is fixed to the box body 100, based on the principle of relative movement, the second wall surface 24 can move in a direction toward the main shaft 31, and the first wall surface 23 can move in a direction toward the main shaft 31. This makes it possible to control the direction of movement of the wall surface and its associated ridges.

[0092] On the other hand, when the second vector perpendicular from the center point of the main axis 31 to the second wall surface 24 has a component that extends in a direction perpendicular to the first side surface on the external environment member 400 (i.e., a component that extends horizontally or laterally as shown in Figures 3 and 9), the second wall surface 24 can be considered to have the inward movement component. As a result, the ridges formed by the intersection of the second wall surface 24 and the other wall surfaces of the door body (for example, the first and second side ridges described later) all have an inward movement component, and interference phenomena with the external environment member 400 can be effectively mitigated.

[0093] On the other hand, when the first vector perpendicular from the first wall surface 23 to the center point of the main axis 31 has a component that extends in a direction parallel to the first side surface on the external environment member 400 (i.e., a component that extends in the vertical or longitudinal direction as shown in Figures 3 and 9), the first vector perpendicular points away from the main axis 31, so the first wall surface 23 can be considered to have the backward movement component. As a result, the first wall surface 23 and the ridges formed by the intersection of it with other walls of the door body (for example, the first side ridge formed by the intersection of it with the second wall surface 24) all have a backward movement component, which strengthens the unity between the door body 200 and the box body 100 and prevents the door body 200 from moving excessively away from the box body 100. If the door body 200 has previously undergone a stage of rotation in its original position (for example, rotating around the main shaft 31 as the axis of rotation, or the sub-shaft moving along the second sub-shaft trajectory line 61), a certain rotation angle is open, so the first wall surface 23 and associated ridges will not interfere with or be compressed by the box body 100.

[0094] In some embodiments, the direction approaching the box 100 can be defined as "rearward," and the direction away from the box 100 can be defined as "forward." This is based on the usage state of the refrigerator.

[0095] When viewed in conjunction with other vector perpendiculars, the second wall surface 24 as a whole moves inward and forward (forward means away from the opening 10 of the box body 100, or away from the opening 10 on the first side surface 41), and the first wall surface 23 as a whole moves inward and backward.

[0096] In response to this, during the closing process of the door body 200, as the main shaft 31 moves along the first main shaft trajectory line 51 relative to the door body 200, the main shaft 31 moves away from the second wall surface 24 while approaching the first wall surface 23. The second wall surface 24 moves outward and backward as a whole, and the first wall surface 23 moves outward and forward as a whole. As a result, the first wall surface 23 can quickly return to its original position outward and avoid being compressed against the box body 100 in the forward direction, and the second wall surface 24 can return to its original position outward as a whole and prevent unnecessary gaps from being created between the door body 200 and the box body 100 at the rear.

[0097] In one embodiment, as shown in Figures 6 and 4, during the process of opening the door body 200, the main shaft 31 further moves along the second main shaft trajectory line 52.

[0098] The main axis trajectory line 5 may include the second main axis trajectory line 52. When the main axis 31 moves along the second main axis trajectory line 52 relative to the door body 200, the main axis 31 moves away from the second wall surface 24 while moving closer to the first wall surface 23. In an embodiment in which the main axis 31 is fixed to the box body 100, based on the principle of relative movement, the second wall surface 24 can move away from the main axis 31, and the first wall surface 23 can move closer to the main axis 31. This makes it possible to control the direction of movement of the wall surface and its associated ridges.

[0099] On the other hand, when the second vector perpendicular from the center point of the main axis 31 to the second wall surface 24 has a component extending in a direction parallel to the first side surface on the external environment member 400 (i.e., a component extending in the vertical or longitudinal direction as shown in Figure 9), the second vector perpendicular points away from the main axis 31, and therefore the second wall surface 24 can be considered to have the backward movement component. As a result, the ridges formed by the intersection of the second wall surface 24 and the other wall surfaces of the door body (for example, the first and second side ridges described later) all have a backward movement component, the door body 200 can be rotated open to a larger angle, and its integration with the box body 100 can be strengthened, and it can also help prevent interference with the external environment member 400.

[0100] On the other hand, when the first vector perpendicular from the first wall surface 23 to the center point of the main axis 31 has a component that extends in a direction perpendicular to the first side surface on the external environment member 400 (i.e., a component that extends horizontally or laterally as shown in Figure 9), the first vector perpendicular points in a direction approaching the main axis 31, and therefore the first wall surface 23 can be considered to have the outward movement component. As a result, the ridges formed by the intersection of the first wall surface 23 and other walls of the door body (for example, the second side ridge formed by the intersection of the first wall surface 23 and the second wall surface 24) all have outward movement components, allowing the door body 200 to rotate and open to a larger angle, and preventing interference or compression between the door body 200 and the box body 100.

[0101] When viewed in conjunction with other vector perpendiculars, the second wall surface 24 moves outward and backward as a whole, while the first wall surface 23 moves outward and forward as a whole.

[0102] In response to this, during the closing process of the door body 200, as the main shaft 31 moves along the second main shaft trajectory line 52 relative to the door body 200, the main shaft 31 approaches the second wall surface 24 while moving away from the first wall surface 23. The second wall surface 24 moves inward and forward as a whole, and the first wall surface 23 moves inward and backward as a whole. As a result, both the second wall surface 24 and the second relief 23 can move inward as a whole, and the door body 200 can achieve the effect of rapid inward movement and return. Furthermore, since the second wall surface 24 is located on the side of the door body 200 that is relatively close to the external environment member 400, the forward movement of the second wall surface 24 can avoid interference with the external environment member 400, and furthermore, based on the backward movement of the first wall surface 23, the swinging closure of the second wall surface 24 can be rapidly initiated.

[0103] During the process of the door body 200 opening, the main shaft 31 moves sequentially along the first main shaft trajectory line 51, the second main shaft trajectory line 52, and the third main shaft trajectory line 53. That is, the main shaft 31 changes in the order of states shown in Figures 4, 5, 3 or 9, 6, 7, and 8. The main shaft 31 starts from the center of the main groove 21 shown in Figures 4 and 5, first moves to an end (or one end of the main shaft trajectory line 5) that is close to the second wall surface 24 and away from the first wall surface 23 in the main groove 21, as shown in Figure 3 or 9, then moves to an end (or the other end of the main shaft trajectory line 5) that is away from the second wall surface 24 and close to the first wall surface 23 in the main groove 21, as shown in Figure 7, and finally returns to the center of the main groove 21 as shown in Figure 8.

[0104] The movement of the shaft to the end of the groove does not necessarily mean that the surface of the shaft comes into contact with the inner wall of the groove. The present invention does not preclude adjusting tolerances between the shaft surface and the inner wall of the groove to provide a gap to prevent structural damage when the shaft moves to a limit position near the inner wall of the groove end.

[0105] Correspondingly, during the closing process of the door body 200, the main shaft 31 moves sequentially along the third main shaft trajectory line 53, the second main shaft trajectory line 52, and the first main shaft trajectory line 51. That is, the main shaft 31 changes in the order of states shown in Figures 8, 7, 6, 3, or 9, 5, 4. The main shaft 31 starts from the center of the main groove 21, first moves to an end that is away from the second wall surface 24 and close to the first wall surface 23 within the main groove 21, then moves to an end that is close to the second wall surface 24 and away from the first wall surface 23 within the main groove 21, and finally returns to the center of the main groove 21.

[0106] The sum of the lengths of the first spindle track 51 and the third spindle track 53 is equal to the length of the second spindle track 52. This not only ensures that the path of the spindle 31 as it reciprocates within the main groove 21 coincides, but also ensures that the initial position P0 and the final position of the entire movement of the spindle 31 coincide. Furthermore, it is possible to shorten the length of the main groove 21, reduce the thickness of the door body 200, maintain the stability of the movement of the door body 200, and even reduce the number of suspension devices (static holding devices (e.g., door stoppers)) within the shaft groove.

[0107] In one embodiment, as shown in Figures 4 and 5, the sub-axis 32 further includes the step of moving along the second sub-axis trajectory line 51.

[0108] When the door body 200 opens and the sub-shaft 32 moves along the second sub-shaft trajectory line 61, the main shaft 31 rotates on its axis, and the door body 200 rotates in place (at its original position) with the main shaft 31 as its axis of rotation.

[0109] During this process, the spindle 31 is held in its initial position P0 relative to the main groove 21.

[0110] In one embodiment, as shown in Figures 3 and 9, the sub-axis 32 further includes the step of moving along the third sub-axis trajectory line 63.

[0111] When the door body 200 opens and the sub-shaft 32 moves along the third sub-shaft trajectory line 63, the sub-shaft 32 approaches the first wall surface 23 while simultaneously approaching the second wall surface 24 relative to the door body 200. This helps to ensure stability during the rotational opening process of the door body 200, and if the distance between the main shaft 31 and the sub-shaft 32 is fixed, the main shaft 31 can be controlled to move away from the sub-shaft 32, thereby controlling the effect of the main shaft 31 moving along the first main shaft trajectory line 51.

[0112] During the process in which the sub-axis 32 moves along the third sub-axis trajectory line 63, there is a stage in which the door body 200 moves away from the external environment member 400. This not only completes the guidance of the movement of the door body 200 through the sub-axis 32, but also enables the door body 200 to move away from the external environment member 400, thereby effectively achieving interference prevention.

[0113] As shown in Figures 8, 7, and 6, in one embodiment, during the process in which the door body 200 opens and the sub-shaft 32 moves along the first sub-shaft trajectory line 64, there is a stage in which the door body 200 moves away from the external environment member 400. This not only completes the guidance of the movement of the door body 200 through the sub-shaft 32, but also, since the first sub-shaft trajectory line 64 is ahead of the fourth sub-shaft trajectory line 62 in the closing stage, the time during which the first sub-shaft trajectory line 64 acts in the opening stage is later, and by moving outward toward the external environment member 400, the door body 200 can be opened to a larger angle, making it easier for the user to put in and take out their items.

[0114] The present invention is not limited to the door body 200 moving away from the external environment member 400 throughout the entire process as the sub-shaft 32 moves along the third sub-shaft trajectory line 63, but may also involve movement in other directions. The present invention is also not limited to the door body 200 having only movement in this process, but may also involve swinging and opening in this process.

[0115] In response to this, during the closing process of the door body 200, there is a stage in which the door body 200 moves in a direction that approaches the external environment member 400 as the sub-shaft 32 moves along the first sub-shaft trajectory line 64. As a result, the pivot side of the door body 200 returns to its original position, and based on the lever principle, the free end of the door body 200 rotates to a smaller angle and returns at a faster speed, enabling the door body 200 to close quickly.

[0116] Specifically, in the state shown in Figure 8, during the closing process of the door body 200, the main shaft 31 moves away from the external environmental member 400, and the door body 200 moves closer to the external environmental member 400 based on the principle of relative movement.

[0117] In one embodiment, as shown in Figures 3, 9, and 6, during the process in which the sub-axis 32 moves along the third sub-axis trajectory line 63 relative to the door body 200, the door body 200 first moves away from the external environment member 400, and then moves closer to the external environment member 400. This controls the door body 200 to move away from the external environment member 400 in the initial stage of rotational opening, preventing interference with the door body 200. In the middle and later stages of rotational opening, it moves closer to the external environment member 400, opening the access port, preventing interference with the internal structure of storage members such as shelves, and is advantageous for opening the door body 200 to a larger angle.

[0118] Specifically, in the state shown in Figure 3 or Figure 9, the main shaft 31 moves relative to the door body 200 in a direction approaching the external environmental member 400, and the door body 200 moves away from the external environmental member 400 based on the principle of relative movement. In the state shown in Figures 9 and 6, after completing the step in which the main shaft 31 moves relative to the door body 200 in a direction approaching the external environmental member 400, there is a step in which the direction of movement of the main shaft 31 reverses and moves away from the external environmental member 400, and the door body 200 moves closer to the box body 100 based on the principle of relative movement.

[0119] Therefore, when the sub-axis 32 moves along the third sub-axis trajectory 63, the main axis 31 first moves along the first main axis trajectory 51, and then moves along the second main axis trajectory 52 (see Figure 6, before the state shown in Figure 6). When the sub-axis 32 moves along the third sub-axis trajectory 63, the door body 200 first moves away from the external environment member 400 while approaching the box body 100, then moves away from the box body 100 while approaching the external environment member 400, and finally moves closer to the box body 100 while approaching the external environment member 400.

[0120] As the main spindle 31 moves along the first main spindle trajectory line 51, the corresponding portion of the main groove 21 on the main spindle 31 always moves in a direction that moves away from the external environmental member 400 and closer to the box body 100, relative to the box body 100 and the external environmental member 400.

[0121] As the main shaft 31 moves along the second main shaft trajectory 52, the corresponding portion of the main groove 21 on the main shaft 31 moves toward the external environmental member 400 and away from the box body 100 with respect to the box body 100 and the external environmental member 400, continuing until the direction of movement of the corresponding portion of the main groove 21 is perpendicular to the first side surface of the external environmental member 400. Thereafter, the corresponding portion of the main groove 21 on the main shaft 31 continues to move toward the external environmental member 400 and closer to the box body 100, continuing until the sub-shaft 32 reaches the end of the third sub-shaft trajectory 63. When the end of the third sub-shaft trajectory 63 and the beginning of the fourth sub-shaft trajectory 62 coincide, you can refer to Figure 9.

[0122] In one embodiment, as shown in Figures 6 and 7, the sub-axis 32 has a step of moving along the fourth sub-axis trajectory line 62.

[0123] As the door body 200 opens and the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, there is a stage in which the sub-shaft 32 moves toward the second wall surface 24 while moving toward the first wall surface 23 relative to the door body 200. This allows the sub-shaft 32 to assist in deepening the rotation angle of the door body 200 after it has opened to a certain angle, thus satisfying the user's need to quickly release the storage space. If the distance between the main shaft 31 and the sub-shaft 32 is fixed during the process of the door body 200 opening to a certain angle, the sub-shaft 32 assists in causing the door body 200 to rotate and move toward the external environment member 400 side at the same time, thereby quickly releasing the access opening, widening the access opening, and satisfying the user's needs.

[0124] In an embodiment where the second sub-axis trajectory line 62 is curved, the process of the door body 200 continuously swinging open becomes smoother.

[0125] In response to this, during the closing process of the door body 200, as the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, there is a stage in which the sub-shaft 32 moves away from the second wall surface 24 while simultaneously moving away from the first wall surface 23 relative to the door body 200. This allows the door body 200 to be closed smoothly and quickly.

[0126] The present invention is not limited to the sub-axis 32 always having movement in the direction described above during the process of moving along the fourth sub-axis trajectory line 62. Before the above-described movement step, the sub-axis 32 may include movement in other directions, and / or after the above-described movement step, the sub-axis 32 may include movement in other directions. As shown in Figures 6 to 8, in one embodiment of the present invention, during the process in which the door body 200 opens and the sub-axis 32 moves along the fourth sub-axis trajectory line 62, the sub-axis 32 first approaches the second wall surface 24 while approaching the first wall surface 23, and then moves away from the first wall surface 23 while approaching the second wall surface 24. This can help reduce the amount of rotation or the ratio of the amount of rotation to the amount of translation, thereby helping to avoid interference and enhance the stability of the movement of the door body 200.

[0127] In response to this, during the closing process of the door body 200, as the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, the sub-shaft 32 first moves away from the second wall surface 24 while approaching the first wall surface 23, and then moves away from the second wall surface 24 while moving away from the first wall surface 23. This shortens the vertical distance between the sub-shaft 32 and the first wall surface 23 in the initial stage, allowing the door body 220 to be controlled from the rotating end face side and quickly returned from a large-angle open state.

[0128] If the sub-shaft 32 only has a movement phase in which it approaches the second wall surface 24 while moving away from the first wall surface 23, that is, in the process in which the door body 200 opens and the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, when the sub-shaft approaches the second wall surface 24 while moving away from the first wall surface 23 relative to the door body 200, at least the ratio of the amount of rotation of the end face can be reduced, preventing interference from occurring, and at the same time a certain amount of space can be left for the user to take out the items.

[0129] In some embodiments, as shown in Figure 3 or Figure 9, Figure 6 and Figure 8, the main shaft 31 has a stage in the process of opening the door body 200 in which it moves at least along the main shaft trajectory line 5. To understand that in the process of opening the door body 200 in which it is understood, the main shaft 31 may have a stage in which it is held in a position in the main groove 21, and this position-holding stage may be present in the early, middle and / or late stages of opening the door body 200.

[0130] As the sub-axis 32 moves along the fourth sub-axis trajectory 62, there is a stage in which the door body 200 moves in a direction that approaches the external environment member 400. This not only completes the guidance of the rotational opening of the door body 200 through the sub-axis 32, but also enables the door body 200 to rotate and open at a large angle, secures space on the access side, expands the space in which the user can take out items in a direction perpendicular to the external environment member 400, and establishes a positional foundation for the subsequent large-angle opening along the first sub-axis trajectory 64. As can be understood, the present invention is not limited to the door body 200 always moving in the direction described above as the process in which the sub-axis 32 moves along the fourth sub-axis trajectory 62, nor is it limited to the door body 200 only undergoing movement.

[0131] In one embodiment, as shown in Figures 6, 7, and 8, during the process in which the sub-axis 32 moves along the fourth sub-axis trajectory line 62 relative to the door body 200, the door body 200 first moves in a direction approaching the external environment member 400, and then moves in a direction away from the external environment member 400. This allows the door body 200 to be controlled to open first toward the external environment member 400, and then the door body 200, particularly the pivot side where the hinge member 300 is provided, to move away from the external environment member 400, thereby achieving the effect of large-angle opening.

[0132] Specifically, in the state shown in Figures 6 and 7, during the opening process of the door body 200, the main shaft 31 moves away from the external environmental member 400 relative to the door body 200, the corresponding groove portion in the main groove 21 moves closer to the external environmental member 400, and the door body 200 moves closer to the external environmental member 400 based on the principle of relative movement. In the state shown in Figures 7 and 8, if the fourth sub-axis trajectory line 62 is extended toward the first sub-axis trajectory line 64 and the direction of movement of the main shaft 31 relative to the door body 200 is reversed, the main shaft 31 moves closer to the external environmental member 400, the corresponding groove portion in the main groove 21 moves away from the external environmental member 400, and the door body 200 moves away from the external environmental member 400 based on the principle of relative movement.

[0133] In yet another embodiment, if the length of the fourth sub-axis trajectory 62 is shortened so that the main shaft 21 always moves away from the external environment member 400 during the process of the sub-axis 32 moving along the fourth sub-axis trajectory 62, then the door body 200 always moves in a direction closer to the external environment member 400 during the process of the sub-axis 32 moving along the fourth sub-axis trajectory 62.

[0134] If we define the direction approaching the external environmental member 400 as "outward" and the direction away from the external environmental member 400 as "inward," then by combining this with the movement state of the door body 200 when the aforementioned sub-axis 32 moves along the second sub-axis trajectory line 61 and the fourth sub-axis trajectory line 62, it is possible to realize an "inward-outward-inward" opening operation process of the door body 200. This effectively balances the movement position of the door body 200 in the inward and outward directions, preventing the door body 200 from excessively turning outward and interfering with the external environmental member 400, and also preventing the door body 200 from excessively turning inward and interfering with the other door body of a double-opening door structure, or causing problems such as occupying the entrance or interfering with internal components.

[0135] In response to this, during the closing process of the door body 200, there is a stage in which the door body 200 moves away from the external environment member 400 as the sub-axis 32 moves along the fourth sub-axis trajectory line 62. This allows the door body 200 to quickly retract inward away from the external environment member 400, thereby increasing the amplitude of the door closing and accelerating the closing process.

[0136] Specifically, in the state shown in Figures 6 and 7, during the closing process of the door body 200, the main shaft 31 moves toward the external environmental member 400 relative to the door body 200, the corresponding groove portion in the main groove 21 moves toward the external environmental member 400, and the door body 200 moves toward the external environmental member 400 based on the principle of relative movement. In the state shown in Figures 7 and 8, if the fourth sub-axis trajectory line 62 is extended toward the first sub-axis trajectory line 64, the main shaft 31 first moves toward the external environmental member 400 before the above process, the corresponding groove portion in the main groove 21 moves toward the external environmental member 400, and the door body 200 moves toward the external environmental member 400 based on the principle of relative movement.

[0137] In the first embodiment of one design, as shown in Figures 6 and 7, when the door body 200 opens and the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, the main shaft 31 moves along the second main shaft trajectory line 52. As the sub-shaft 32 moves along the fourth sub-shaft trajectory line 62, the door body 200 approaches the box body 100 while also approaching the external environment member 400. This prevents the door body 200 from obstructing the opening of the box body 100 and prevents the door body 200 and the box body 100 from separating.

[0138] In the second embodiment of this design, when the door body 200 opens and the sub-axis 32 moves along the fourth sub-axis trajectory 62, the main axis 31 can first move along the second main axis trajectory 52 to control the door body 200 to move closer to the external environment member 400, and then move along the third main axis trajectory 53 to control the door body 200 to move away from the external environment member 400. This situation can occur in an embodiment in which the fourth sub-axis trajectory 62 shown in Figures 6 and 7 and the first sub-axis trajectory 64 shown in Figure 8 are unified and defined as the second sub-axis trajectory.

[0139] In one embodiment, as shown in Figure 8, when the door body 200 opens and the sub-shaft 32 moves along the first sub-shaft trajectory 64, the main shaft 31 moves along the third main shaft trajectory 53. As the sub-shaft 32 moves along the first sub-shaft trajectory 64, the door body 200 moves away from the box body 100 while moving away from the external environment member 400. This helps the door body 200 to open to a larger angle and ensures that the door body 200 does not interfere with the external environment member 400.

[0140] In an embodiment having a second sub-axis trajectory line 61, the second sub-axis trajectory line 61 can be configured as a single arc, a combination of multiple arcs, or as an irregular arc shape overall.

[0141] The second sub-axis track line 61 is a circular arc with equal radii overall, which helps to achieve smooth rotation of the door body 200 in its original position.

[0142] In the first embodiment, the radius of curvature of the second sub-axis trajectory 61 is smaller than the radius of curvature of the fourth sub-axis trajectory 62. In the second embodiment, the curvature of the second sub-axis trajectory 61 is greater than the curvature of the fourth sub-axis trajectory 62. In the third embodiment, the two conditions described above are simultaneously satisfied between the second sub-axis trajectory 61 and the fourth sub-axis trajectory 62.

[0143] If the second sub-axis trajectory line 61 and / or the fourth sub-axis trajectory line 62 is a single circular arc, the curvature or radius of curvature may be the curvature or radius of curvature of that single circular arc. If the second sub-axis trajectory line 61 and / or the fourth sub-axis trajectory line 62 is a combination of multiple circular arcs or an irregular arc shape, the curvature or radius of curvature may be the average curvature or radius of curvature of that arc.

[0144] In an embodiment having a third sub-axis trajectory line 63, the third sub-axis trajectory line 63 is linear as a whole, and may be a single straight line or may be formed by a combination of multiple straight sections.

[0145] In an embodiment having a first sub-axis trajectory line 64, the first sub-axis trajectory line 64 is linear as a whole, and similarly, it may be a single straight line as a whole, or it may be formed by a combination of multiple straight sections.

[0146] The main shaft trajectory line 5 is elliptical in shape as a whole, which allows for smoother rotation and opening of the door body 200 during the process in which the sub-shaft 32 moves along the third sub-shaft trajectory line 63 or the process in which the sub-shaft 32 moves along the first sub-shaft trajectory line 64. The third main shaft trajectory line 53, the first main shaft trajectory line 51, and the second main shaft trajectory line 52 are all included in the main shaft trajectory line 5.

[0147] You can choose one of the four types of movement processes described above to create a configuration, or you can combine several of them to create a configuration.

[0148] There is an "and / or" relationship between the four types of movement processes described above.

[0149] In response to this, the above-described technical method of the present invention can achieve the technical effect of smoother and faster rotational closing. The following processes can be carried out sequentially during the closing process of the door body 200. As shown in Figure 8, the sub-shaft 32 moves along the first sub-shaft trajectory 64 and the main shaft 31 moves along the third main shaft trajectory 53; as shown in Figures 6 and 7, the sub-shaft 32 moves along the fourth sub-shaft trajectory 62 and the main shaft 31 moves along the second main shaft trajectory 52; as shown in Figures 3 and 9, the sub-shaft 32 moves along the third sub-shaft trajectory 63 and the main shaft 31 first moves along the second main shaft trajectory 52 and then moves along the first main shaft trajectory 51; as shown in Figures 4 and 5, the sub-shaft 32 moves along the second sub-shaft trajectory 61 and the main shaft 31 rotates, and the door body 200 rotates in place with the main shaft 31 as the axis of rotation.

[0150] In this first embodiment, the main shaft 31, the sub-shaft 32, and the door body 200 can satisfy multiple relative positional relationships.

[0151] The storage member provided in the first embodiment of the present invention can satisfy at least one of the following relationships. To make it clear, the following positional relationships may be AND or OR.

[0152] As shown in Figure 5, in one embodiment, when the sub-shaft 32 moves to the end of the second sub-shaft trajectory line 61, the main shaft 31 can always maintain its initial position P0 relative to the main groove 21. At this time, the opening angle of the door body 200 may be around 14 degrees, for example, 10 degrees, 12 degrees, 14 degrees, 16 degrees, 18 degrees, 20 degrees, etc.

[0153] As shown in Figure 3 or Figure 9, in one embodiment, when the main shaft 31 moves to the end of the first main shaft trajectory 51, the sub-shaft 32 can be positioned on the third sub-shaft trajectory 63. At this time, the opening angle of the door body 200 may be around 45 degrees, for example, 40 degrees, 43 degrees, 45 degrees, 47 degrees, 50 degrees, etc.

[0154] In one embodiment, when the main shaft 31 moves along the second main shaft trajectory line 52 and returns to the initial position P0 (see the state before the state shown in Figures 9 and 6), the sub-shaft can be positioned on the third sub-shaft trajectory line 63. At this time, the opening angle of the door body 200 may be around 70 degrees, for example, 65 degrees, 70 degrees, or 75 degrees.

[0155] As shown in Figures 6 and 9, in one embodiment, when the sub-shaft 32 moves to the end of the third sub-shaft trajectory 63 (which may be the starting end of the fourth sub-shaft trajectory 62 in one embodiment), the main shaft 31 can be positioned between its initial position and the end of the second main shaft trajectory 52. ​​At this time, the opening angle of the door body 200 may be around 80 degrees, for example, 78 degrees, 80 degrees, 82 degrees, 85 degrees, etc.

[0156] As shown in Figure 7, in one embodiment, when the sub-shaft 32 moves to the end of the fourth sub-shaft trajectory 62, the main shaft 31 can be positioned at the end of the second main shaft trajectory 53 (or the end of the main groove 21 that is close to the first wall surface 23). At this time, the opening angle of the door body 200 may be around 90 degrees, for example, 88 degrees, 90 degrees, 92 degrees, 95 degrees, 97 degrees, 100 degrees, etc.

[0157] As shown in Figure 8, in one embodiment, when the sub-shaft 32 moves to the end of the first sub-shaft trajectory 64, the main shaft 31 moves to the end of the third main shaft trajectory 63 and returns to the initial position P0. At this time, the opening angle of the door body 200 may be around 110 degrees, for example, 105 degrees, 110 degrees, 115 degrees, 118 degrees, 120 degrees, etc.

[0158] Furthermore, as shown in Figures 3 to 10, the first embodiment of the present invention may include the following technical details.

[0159] The storage member is positioned on the side of the external environment member 400, and the door body 200 includes a third wall surface 25 and a second wall surface 24 that are perpendicular to each other. When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 is close to the first side surface 41 of the external environment member 400. The third wall surface 25 is away from the plane in which the opening 10 is located and is parallel to that plane, and the second wall surface 24 is close to the first side surface 41 and is parallel to the first side surface 41.

[0160] The third wall surface 25 and the second wall surface 24 intersect to form the first side ridge 26.

[0161] The door body further includes a first wall surface 23 perpendicular to the second wall surface 24. When the door body 200 closes the opening 10 of the box body 100, the first wall surface 23 is close to and parallel to the plane in which the opening 10 exists.

[0162] The first wall surface 23 and the second wall surface 24 intersect to form the second side ridge 27.

[0163] In some embodiments, during the process of opening the door body 200, the first side ridge 26 moves along the first outer ridge trajectory L11.

[0164] The first outer ridge trajectory L11 is arc-shaped overall and protrudes away from the door body 200.

[0165] During this process, the door body 200 rotates in place with the main shaft 31 as its axis of rotation, while the secondary shaft 32 moves along the second secondary shaft trajectory line 61.

[0166] The first ridge 26 continues to move along the second outer ridge trajectory L12.

[0167] The second outer ridge trajectory L12 is linear overall.

[0168] The aforementioned straight line may be a strictly straight line, or it may be an approximate straight line with deformation within a certain error range. Further explanation will not be provided below.

[0169] In this process, the main axis 31 first moves along the first main axis trajectory line 51 in a direction approaching the first side ridge 26, and then moves along the second main axis trajectory line 52 in a direction away from the first side ridge 26. The secondary axes move sequentially along the third secondary axis trajectory line 63 and the fourth secondary axis trajectory line 62.

[0170] During the opening of the door body 200, the main shaft 31 reciprocates within the main groove 21. The main groove 21 is elliptical in shape overall. The main shaft trajectory line 5 formed by the main shaft 31 within the main groove 21 can protrude away from the second wall surface 24.

[0171] In an embodiment where the first wall surface 23 and the second wall surface 24 intersect to form a second side ridge 27, the main groove 21 can protrude in a direction away from the second side ridge 27. As the door body 200 opens, the sub-shaft 32 moves sequentially along a curved trajectory (e.g., a second sub-shaft trajectory 61), a straight trajectory (e.g., a third sub-shaft trajectory 63), and a curved trajectory (e.g., a fourth sub-shaft trajectory 62).

[0172] In some embodiments, during the process of opening the door body 200, the first side ridge 26 moves along the second outer ridge trajectory L12.

[0173] The second outer ridge trajectory L12 is linear overall.

[0174] In this process, the main axis first moves along the first main axis trajectory 51 in a direction approaching the first side ridge 26, and then moves along the second main axis trajectory 52 in a direction away from the first side ridge 26. The secondary axes move sequentially along the third secondary axis trajectory 63 and the fourth secondary axis trajectory 62.

[0175] The first ridge 26 continues to move along the third outer ridge trajectory L13, undergoing a curved movement with a changing radius of curvature.

[0176] The third outer ridge trajectory L13 is composed of at least two curves with different mean radii of curvature, or at least two points on the third outer ridge trajectory L13 have different radii of curvature.

[0177] In this process, the main shaft 31 always moves along the third main shaft trajectory 53 in a direction approaching the first side ridge 26, or the main shaft 31 first moves along the second main shaft trajectory 52 and then along the third main shaft trajectory 53. The secondary shaft 32 always moves along the first secondary shaft trajectory 64, or the secondary shaft 32 moves sequentially along the fourth secondary shaft trajectory 62 and the first secondary shaft trajectory 64.

[0178] In some embodiments, during the process of the door body 200 opening, the first side edge 26 can move in a straight line along the second outer edge trajectory L12.

[0179] The aforementioned linear movement may be an exact linear movement or an approximate linear movement with deformation within a certain error range. Further explanation will not be provided below.

[0180] The second outer ridge trajectory L12 is a straight line that extends perpendicularly to the direction of the opening 10 of the box body 100. This straight line may be formed by a curve or combination of curves with a relatively large radius of curvature and / or relatively small curvature, and may be formed by a single straight line or a combination of multiple straight lines.

[0181] Specifically referring to Figure 10, in this process, the first side edge 26 has a first nearest point T0 with respect to the external environment member 400 (particularly the first side surface 41), and the first side edge 26 has a first furthest point T1 with respect to the external environment member 400 (particularly the first side surface 41). The first nearest point T0 lies on the second outer edge trajectory L12, and its vertical distance from the first side surface 41 is the shortest compared to other points on the outer edge trajectory. The first furthest point T1 lies on the second outer edge trajectory L12, and its vertical distance from the first side surface 41 is the longest compared to at least other points on the second outer edge trajectory L12.

[0182] The distance between the first nearest position T0 and the first furthest position T1 in the first direction F1 is 0.5 mm or less. This distance is the difference obtained by subtracting the vertical distance between the first nearest position T0 and the first side surface 41 from the vertical distance between the first furthest position T1 and the first side surface 41.

[0183] The aforementioned first direction F1 is perpendicular to the first side surface 41.

[0184] The first outer ridge trajectory L12 is located in a first plane, and the first plane is perpendicular to the first side surface 41. A first straight line is obtained by drawing a straight line parallel to the first side surface 41 on the first plane, passing through the farthest point on the first outer ridge trajectory L12 from the first side surface 41 (for example, the first farthest position T1). A second straight line is obtained by drawing a straight line parallel to the first side surface 41 on the first plane, passing through the nearest point on the first outer ridge trajectory L12 from the first side surface 41 (for example, the first nearest position T0).

[0185] During the process in which the first side ridge 26 moves along the second outer ridge trajectory L12, the second outer ridge trajectory L12 can be considered to be located between the first straight line and the second straight line. The distance between the first straight line and the second straight line is 0.5 mm or less.

[0186] When the second outer ridge trajectory L12 extends linearly along the second direction F2 as a whole, the distance between the first nearest point T0 and the first furthest point T1 in the first direction F1 is 0.2 mm or less.

[0187] The second direction F2 is perpendicular to the plane in which the opening 10 of the box body 100 exists.

[0188] During the process in which the first side ridge 26 moves along the second outer ridge trajectory L12, the second outer ridge trajectory L12 can be considered to be located between two straight lines. When the second outer ridge trajectory L12 is straight, the distance between the two straight lines is 0.2 mm or less. Both of the two straight lines are parallel to the first side surface 41.

[0189] In some embodiments, during the process of the door body 200 opening, the first side edge 26 undergoes a curved movement along the third outer edge trajectory L13, with a changing radius of curvature. The first side edge 26 undergoes at least an arc movement along the first outer edge trajectory L11, and the first outer edge trajectory L11 protrudes away from the door body 200.

[0190] The aforementioned circular arc movement may be an exact circular arc movement, or it may be an approximate circular arc movement with deformation within a certain error range. Further explanation will not be provided below.

[0191] The first ridge 26 moves sequentially along the first outer ridge trajectory L11 and the third outer ridge trajectory L13.

[0192] The first outer ridge trajectory L11 is arc-shaped overall, and when the first side ridge 26 moves along the first outer ridge trajectory L11, the door body 200 can rotate in place. A second outer ridge trajectory L12 can exist between the first outer ridge trajectory L11 and the third outer ridge trajectory L13.

[0193] The second outer ridge trajectory L12 is linear overall.

[0194] In some embodiments, the second side ridge 27 moves along the first inner ridge trajectory L21.

[0195] The first inner ridge trajectory L21 is arc-shaped overall and protrudes away from the door body 200.

[0196] During this process, the door body 200 rotates in place with the main shaft 31 as its axis of rotation, while the secondary shaft 32 moves along the second secondary shaft trajectory line 61.

[0197] The second side ridge 27 continues to move sequentially along the second inner ridge trajectory L22 and the third inner ridge trajectory L23.

[0198] The mean radius of curvature of the second inner ridge locus L22 is different from the mean radius of curvature of the third inner ridge locus L23.

[0199] At least two points on the second inner ridge trajectory L22 have different radii of curvature, and / or at least two points on the third inner ridge trajectory L23 have different radii of curvature.

[0200] In this process, the main axis 31 first moves along the first main axis trajectory 51 in a direction approaching the first side ridge 26, then moves along the second main axis trajectory 52 in a direction away from the first side ridge 26, and finally moves along the third main axis trajectory 53 in a direction approaching the first side ridge 26. The sub-axis moves sequentially along the third sub-axis trajectory 63, the fourth sub-axis trajectory 62, and the first sub-axis trajectory 64.

[0201] During the opening of the door, the main shaft 31 reciprocates within the main groove 21. The main groove 21 is elliptical in shape overall. The main groove 21 extends in the direction of the first side edge 26. The main shaft trajectory line 5 formed by the main shaft 31 within the main groove 21 can project away from the second wall surface 24.

[0202] In an embodiment where the first wall surface 23 and the second wall surface 24 intersect to form a second side ridge 27, the main groove 21 can protrude in a direction away from the second side ridge 27. As the door body 200 opens, the sub-shaft 32 moves sequentially along a curved trajectory (e.g., second sub-shaft trajectory 61), a straight trajectory (e.g., third sub-shaft trajectory 63), a curved trajectory (e.g., fourth sub-shaft trajectory 62), and a straight trajectory (e.g., first sub-shaft trajectory 64).

[0203] In some embodiments, the current position of the main spindle 31 or the sub-spindle 32 relative to the groove can be defined using the center points of the main spindle 31 and the sub-spindle 32. For example, the starting point of the first main spindle trajectory line 51 is defined as the first main spindle reference point D11. The starting point of the second main spindle trajectory line 52 is defined as the second main spindle reference point D12. The starting point of the third main spindle trajectory line 53 is defined as the third main spindle reference point D13. For example, the starting point of the second sub-spindle trajectory line 61 is defined as the first sub-spindle reference point D21. The starting point of the third sub-spindle trajectory line 63 is defined as the second sub-spindle reference point D22. The starting point of the second sub-spindle trajectory line 61 is defined as the third sub-spindle reference point D23. The starting point of the first sub-spindle trajectory line 64 is defined as the fourth sub-spindle reference point D24.

[0204] When the secondary axis 32 is located at the first secondary axis reference point D21, the primary axis 31 is located at the first primary axis reference point D11. When the secondary axis 32 is located at the second secondary axis reference point D22, the primary axis 31 is located at the first primary axis reference point D11. When the secondary axis 32 is located at the third secondary axis reference point D23, the primary axis 31 is located between the first primary axis reference point D11 and the third primary axis reference point D13. When the secondary axis 32 is located at the fourth secondary axis reference point D24, the primary axis 31 is located at the third primary axis reference point D13.

[0205] The distance between the first secondary axis reference point D21 and the first principal axis reference point D11 is equal to the first axis distance, and the distance between the second secondary axis reference point D22 and the first principal axis reference point D11 is equal to the second axis distance.

[0206] The distance between the first axes is equal to the distance between the second axes.

[0207] The first reference circle C1 is drawn with the first principal axis reference point D11 as the center and the distance between the first and second axes as its radius. Both the first secondary axis reference point D21 and the second secondary axis reference point D22 lie on the first reference circle C1.

[0208] The angle between the line connecting the first secondary axis reference point D21 and the first primary axis reference point D11, and the line connecting the second secondary axis reference point D22 and the first primary axis reference point D11, is approximately 14 degrees.

[0209] On the first reference circle C1, the central angle of the arc portion from the first secondary axis reference point D21 to the second secondary axis reference point D22 is approximately 14 degrees.

[0210] The distance between the third sub-axis reference point D23 and the first major axis reference point D11 is equal to the third axis distance, and the distance between the fourth sub-axis reference point D24 and the first major axis reference point D11 is equal to the fourth axis distance.

[0211] The third inter-axis distance is greater than the first inter-axis distance and the second inter-axis distance. The fourth inter-axis distance is greater than the first inter-axis distance and the second inter-axis distance.

[0212] The distance between the four axes is greater than the distance between the third axis.

[0213] The distance between the first principal axis reference point D11 and the second wall surface 24 is equal to the first width distance, and the distance between the first principal axis reference point D11 and the third wall surface 25 is equal to the first thickness distance.

[0243] All explanatory diagrams of the embodiments provided above are based on a technical plan in which the shaft is fixed to the box body 100 and the groove is fixed to the door body 200.

In technical proposals based on such modifications, those skilled in the art can achieve the effects provided above by adjusting the direction of movement of the shafts.

[0245] Such changes in the position of the shaft groove may be included within the scope of protection of the present invention, provided that they do not depart from the concept of the present invention.

[0246] Although the embodiments provided above primarily describe the door-opening process, those skilled in the art can derive alternatives for the door-closing process.

[0247] In one embodiment, the storage member is positioned on the side of the external environment member 400, and the door body 200 includes a third wall surface 25 and a second wall surface 24 perpendicular to each other. When the door body 200 closes the opening 10 of the box body 100, the hinge member 300 is close to the first side surface 41 of the external environment member 400. The third wall surface 25 is away from the plane in which the opening 10 is located and parallel to that plane, and the second wall surface 24 is close to the first side surface 41 and parallel to the first side surface 41. The third wall surface 25 and the second wall surface 24 intersect to form a first side ridge 26.

[0248] As the sub-axis 32 moves to the end of the second sub-axis trajectory line 61 and the door body 200 opens further from this position, the distance in the first direction F1 between the first nearest position T0 of the first side edge 26 with respect to the external environment member 400 and the first furthest position T1 of the first side edge 26 with respect to the external environment member 400 is 0.5 mm or less.

[0250] The first direction F1 is perpendicular to the first side surface 41, and the second direction F2 is perpendicular to the plane in which the opening 10 of the box body 100 is located.

[0251] Based on the above, the storage member provided by the present invention can improve the stability of the swing by setting a stage in which the sub-axis moves along a straight line during the swinging process of the door body.

[0252] In one embodiment, during the process of opening the door, the shaft that guides the rotation of the door is arranged to move along a straight line, and the shaft that drives the rotation of the door is arranged to move along a curve. This not only allows the door to rotate normally, but also avoids damage to the shaft due to abnormal interference caused by machining factors between the shaft grooves, thereby extending the service life and reducing costs. By arranging the sub-shaft and main shaft to move linearly and simultaneously, respectively, and in a curved direction, the amount of position change of the main shaft is reduced compared to conventional technology when opening to the same angle, making the rotational opening process of the door more stable and assisting in the rapid opening of the door.

[0253] In one embodiment, during the process of opening the door, the axis that guides the rotation of the door is arranged to first move along a straight trajectory and then along a curved trajectory. This assists in generating movement in the door first, followed by rotation, and by adjusting the lengths of the two trajectories, self-adaptation (automatic adaptation) can be achieved. Furthermore, by arranging the curved trajectory as a whole to be located on the door-opening direction side of the straight trajectory, smoothness during the door-opening process can be effectively improved, and deterioration and damage due to structural interference over time can be avoided.

[0254] In one embodiment, during the process of closing the door, the axis that guides the rotation of the door is arranged to first move along a straight trajectory and then along a curved trajectory. This assists in generating movement in the door first, followed by rotation, and by adjusting the lengths of the two trajectories, self-adaptation (automatic adaptation) can be achieved. Furthermore, by arranging the curved trajectory to be located on the closing direction side of the straight trajectory as a whole, smoothness during the closing process can be effectively improved, and deterioration and damage due to structural interference over time can be avoided.

[0255] This specification is described in accordance with embodiments, but each embodiment does not necessarily contain only a single, independent technical solution. This method of description is for clarity, and those skilled in the art should view the specification as a whole. The technical solutions of each embodiment can be appropriately combined to form other embodiments that will be understood by those skilled in the art.

[0256] The series of detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention and do not limit the scope of protection of the present invention.
